Douglas,
This is a "not-yet-implemented" bug: the view doesn't use the general
formatting facility to render the groups' labels. The problem is located
in the file
http://static.simile.mit.edu/exhibit/api-2.1.0/scripts/ui/views/tile-view.js
Look for the function
Exhibit.TileView.prototype._reconstruct
Look for this code
this._orderedViewFrame.onNewGroup = function(groupSortKey, keyType,
groupLevel) {
closeGroups(groupLevel);
var groupDom = Exhibit.TileView.constructGroup(groupLevel,
groupSortKey);
state.div.appendChild(groupDom.elmt);
state.div = groupDom.contentDiv;
state.groupDoms.push(groupDom);
state.groupCounts.push(0);
};
Instead of
var groupDom = Exhibit.TileView.constructGroup(groupLevel,
groupSortKey);
there should be
var groupDom = Exhibit.TileView.constructGroup(groupLevel,
view._uiContext.getFormatter(keyType).formatText(groupSortKey));
But you'd also need to add the getFormatter method to the UIContext class
Exhibit.UIContext.prototype.getFormatter = function(valueType) {
var f;
if (valueType in this._formatters) {
f = this._formatters[valueType];
} else {
f = this._formatters[valueType] =
new Exhibit.Formatter._constructors[valueType](this);
}
return f;
};
